RSA0E821MCN1GS

The RSA0E821MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 820 µF capacitance at 2.5 V. Engineered for compact, high-capacitance applications, it combines low equivalent series resistance (ESR) and high ripple-current capability in a φ6.3 × 7.7 mm SMD package.

Designed for general-purpose electronic designs that require robust bulk capacitance and stable performance over a wide temperature range, the part delivers a balance of long-life endurance, low loss, and compact footprint.

Key Features

• High Capacitance: 820 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk-storage in a small SMD can (φ6.3 × 7.7 mm).
• Low ESR & Low Loss: ESR of 10 mΩ at 20°C/100 kHz and tanδ of 0.12 (20°C, 120 Hz) reduce voltage drop and dissipation under AC stress.
• High Ripple Current Handling: Rated ripple current up to 430 mA at 120 Hz and 4.3 A at 300 kHz, enabling effective smoothing under both low- and high-frequency excitation.
• Compact Surface-Mount Package: Surface-mount radial can in a φ6.3 × 7.7 mm body with recommended land size 6.5 × 6.5 mm for PCB integration.
• Wide Operating Temperature & Long Life: Rated for −55°C to +105°C with a load life of 2000 hours at 105°C under rated voltage.
• Low Leakage Current: Leakage current specified at 700 µA (after 2 minutes at 25°C), suitable for many power and decoupling applications.
• Manufacturing & Compliance: Lead-free reflow soldering compatible (260°C peak per manufacturer guidance) and RoHS compliant.

Typical Applications

• General-purpose power filtering: Bulk capacitance and low ESR support smoothing and decoupling tasks where 820 µF at 2.5 V is required.
• High-frequency decoupling: High ripple-current rating at 300 kHz makes the part suitable for circuits with significant HF switching components.
• Compact power modules: Small φ6.3 × 7.7 mm SMD form factor enables high-capacitance integration in space-constrained PCB layouts.

Unique Advantages

• High charge-storage in a small package: 820 µF nominal capacitance in a φ6.3 × 7.7 mm SMD can reduces board area compared with larger radial solutions.
• Improved thermal endurance: 2000-hour life at 105°C provides predictable long-term behavior in elevated-temperature environments.
• Low loss under AC load: 10 mΩ ESR at 100 kHz and tanδ 0.12 minimize power dissipation and heating during ripple current stress.
• Versatile ripple performance: Specified ripple current at both low (120 Hz) and high (300 kHz) frequencies supports mixed-frequency power designs.
• Production-ready packaging: Supplied in embossed carrier taping with moisture-proof packing for automated SMT assembly.
